Error Code P0A76: What It Means & What To Do?

<<See All OBD Codes

So the OBD code P0A76 is flashing, and the check engine light is on. You don’t have a clue what that means, but don’t worry, we will give you all the information you need to know about the code, what the issue is and how to resolve it easily. This is a generic OBD-II vehicle code, and is known as a Generator Phase W Current Low. When the Engine Control Unit which is the high voltage control module detects a failure in the sensors monitoring current  it will set P0A76 code.

High voltage current of the HV battery and the alternating current for MG1/MG2 is converted by the inverter. This inverter has a three-phase bridge circuit consisting of 6 power transistors for each MG1 and MG2.  These are present so that the direct current and the three phase alternating current can be converted. ECU receives information from the inverter about the amperage and voltage this helps in maintaining effective control. When the ECU notices that the inverter current sensors aren't working as needed i will set P0A76 code and the check engine light will turn on.

What causes this problem with the Generator Phase W Current Low

• Problem with the Inverter With Converter Assembly
• Open or shorted Inverter With Converter Assembly harness
• Poor electrical connection in the Inverter With Converter Assembly circuit

The diagnosis of P0A76 have to be carried out very efficiently, if you think you won’t be able to do it on your own and need professional help, then feel free to approach a professional vehicle diagnostician for it and resolve your issue properly. However, if you want to solve it yourself then follow the steps below:

Begin your diagnosis by getting your OBD scanner and connect it to the diagnostic port of your vehicle. Make sure you retrieve all the codes and freeze fame the data also, remember to make note of them all in the order of appearance. If you are able to find any codes set prior to P0A76, then you will have to resolve them first. Previous codes can cause other error codes to set as well, so it’s important that they are taken care of first. After making note of all the codes, clear them and take your vehicle on a test drive to see if the code resets or if the PCM enters readiness more. If the latter happens, then you are having an intermittent condition, this condition may have to worsen before accurate diagnosis can be made. If the code is reset, then you will have to start your diagnosis, the first step is to check all of the electrical system connected with this issue.

Thoroughly check all the wires, circuits, connectors, harnesses etc. for damages like burning, breaks, corrosion, short etc. If you are able to find any of these issues, simply  repair and correct them or opt for replacement. After you have sorted the circuitry you will have to clear the codes and again go on a test drive. Wait to see if the code returns or the PCM enters readiness mode.If you find that the code is reset, then you will have to check all the parts pertaining to this problem. For this you will require your specific vehicles Technical Service Bulletins or TSB. Match them to the year of manufacture, make, model and engine. Once you have found it, match the symptoms and the error code P0A75 and see what diagnostic steps are mentioned in the TSB. Apart from having diagnostic steps the TSB will also have details of the parts and components related to this error. All the manufacturer specified configurations will also be present. Use the directions given by the TSB to fix your problem, the connector pin-out charts, and circuit flow charts etc will be extremely helpful and enable you to avoid any misdiagnoses.

Common Mistakes When Diagnosing the P0A76 Code

• Not following the Diagnostic procedure step-by-step
• Concluding an issue with the ECU when the wires may be damaged and require repairs/replacements
